GeForce 8600 GT 1GB DDR2 vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has set the core speed at 837 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this card. It features 2688 SPUs along with 224 Texture Address Units and 48 Rasterization Operator Units.

GeForce 8600 GT 1GB DDR2		47 Watts
GeForce GTX Titan		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

Performance-wise, the GeForce GTX Titan should in theory be quite a bit superior to the GeForce 8600 GT 1GB DDR2 in general. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 275584 (2153%)

Texel Rate

The GeForce GTX Titan is much (approximately 2070%) better at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 178848 (2070%)

Pixel Rate

The GeForce GTX Titan should be a lot (about 830%) more effective at anti-aliasing than the GeForce 8600 GT 1GB DDR2, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 35856 (830%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
